my 4 year old tivo died, i had a B drive in it that is 200 Gb i just bought a new tivo, activated the service, updated the tivo and now i want to upgrade the single drive to the 200Gb drive from my old tivo. what do i have to do first to the 200 Gb drive that has data on it? i want to clean the drive and do a direct copy over of the new tivo drive and put the 40 gigger on a shelf in case the 200 gig ever dies. there are no programs on it yet (the 40 gig) but the 200 gig needs to be cleaned like new first IIRC. i can flush the MBR and write zeros to the drive but i want to know if ill be wasting my time. thanx!! Steve.
